$\huge\colorbox{cyan}{☆Answer☆}$

The Ganges River originates in the Himalaya Mountains at Gomukh, the terminus of the Gongotri Glacier. When the ice of this glacier melts, it forms the clear waters of the Bhagirathi River. As the Bhagirathi River flows down the Himalayas, it joins the Alaknanda River, officially forming the Ganges River.
